I just got my hands on a Z3 image on a Toshiba 40gig hard drive & did the upgrade. Most everything looks the same. Voice reconition seems to work much better than the Z2 version did. Haven't had a lot of time to play with the maps yet, but turn by turn guidence also seems to be alot smoother than the Z2 was. This is just my first impression.
I also have a hard drive duplicator and can make an image for anyone willing to supply a 40 gig hard drive and pay your shipping. Not wanting to make any money on this, just want to help fellow Z oners out. If I can anyone with any info on this I will do my best. ![]()
